Goals of EOC
- Help you to make the right moves based on the statistics of Grandmasters and the chess
history of 150 years.
- If you need help in a position just ask the EOC of 50,000,000 (50 million) unique
positions and then make up your mind which move to play.
- An unique reference for opening preparation because all the major games of the last 150
years are in EOC.
Alternative goals of EOC
- Allow REBEL to make use of EOC.
- REBEL is able to use EOC as a normal opening book! Ever seen an opening book of 50,000,000
(50 million) unique opening positions?
- Allow REBEL to consult EOC and depending what is found REBEL will adjust its play playing
the good moves and avoiding the bad moves found in the 50,000,000 chess tree. We believe
it makes REBEL a stronger player.
Especially the last option is a total new development in computer chess as the chess
engine within a second is able to consult the complete human chess history, draw its
conclusions, filter the bad moves and stimulate the good moves.
It's really nice to see REBEL playing pawn sacrifices of Grandmasters on its own because of EOC.
Or simply playing 2.c4 after 1.d4 d5 on its own without the need of an opening book. Another
nice example of EOC comes from the recent match Rebel-Anand. In the last tournament game the
following position was reached.
REBEL10 - Vishy Anand
Position after 10.. Qc8!?
After this move Rebel10 was out of book and played 11. Bb5 a good move as Anand later confirmed.
After the game there was a huge discussion in several Internet chess groups. Rebel should have
played the interesting pawn sacrifice 11. d5?!
No doubt this is an interesting alternative for a computer to play against a top grandmaster
like Anand as the EOC reports 2 won games after 11. d5?! both won for white and therefore
REBEL10 (when EOC is active) will play the move 11. d5?! on the 10th ply because of the help
Which move is better? 11. Bb5 or 11. d5?! Rebel played without EOC against Anand. Should Rebel
have played with EOC? We don't know the answer. Both moves look good. Let's say the last word is
up to the better analists amomg us. In the meantime we consider this option as very useful
for further investigation to improve Rebel's playing strength even more the coming years.

With all these information it is not so difficult to find out if a move is good or bad. For
example: If a move scores more than 55% and the move is played more than 100 times and the
average elo is greather than 2500, then it looks very safe to play this move. As an extra you
can also rely on the Rebel score.
But the REBEL concept of EOC goes a few steps further. A second part of valuable
information (more text related) is also available . Again the chosen example is the

Rebel will display all these information on your screen within a second for every new
position. By clicking on the moves you in the most convenient way can scroll through the
whole EOC of 50 million unique chess positions.
- This overview from the chess tree gives you a list of TOP rated Grandmasters who ever
played the move and what is more important the number of times the Grandmaster has played
that move. Very useful to make up your mind if a move is good enough to play.
- The REBEL tree keeps track of the world's famous 60 chess players. You will find the
names of the super old goodies like Steinitz, Tarrasch, Morphy and so on back in the REBEL
- Also the statistic is interesting for book preparation. Looking at the
above output one may conclude Anand doesn't like to open with 1.d4, 1.c4 or 1.Nf3 but
clearly prefers 1.e4
